Privacy Policy

Last updated: April 14, 2026

What we store and what we discard

What we immediately discard

Your uploaded file — whether code, a document, notes, or a conversation export — is analyzed and immediately discarded after your Patent PreCheck Score is generated. We do not retain, copy, transmit, or store the content of your uploaded file.

What we retain (your analysis profile)

To provide our core service — including project-specific legal change alerts — we retain a structured analysis profile derived from your submission. This profile contains no code, no text from your document, and no personally identifying content from your file. It consists solely of:

• Your Patent PreCheck Score (a number from 0–100)
• Your score band (Not yet ready / Building strength / Strong position / File-ready)
• High-level categorical risk flags, for example:
  • Whether your work appears to have international distribution scope
  • AI contribution level (low / medium / high) — not the AI content itself
  • Technology domain (e.g. software-AI, software-general, hardware)
  • Section 101 risk level (low / moderate / high)
  • Human conception strength (strong / moderate / weak)
• The date of analysis
• The project name you assigned (if you created an account)

How we use your analysis profile for alerts

When new case law, USPTO guidance, or international IP developments occur, we compare each development against stored risk flags to determine who it may affect. For example:

• A ruling about overseas software reproduction damages is sent only to users whose profile flagged international_distribution: true
• New USPTO guidance on AI inventorship is sent only to users whose profile flagged ai_contribution_level: medium or high
• A development affecting all software patents is sent to all users with technology_domain: software

We never use a stored profile to reconstruct your original code, document, or conversation. The flags are categorical — they describe characteristics of your work without containing any of its content.

Account holders

If you create an account, we additionally store your name, email address, and the project names you assign. You may delete your account and all associated data at any time by emailing privacy@patentprecheck.com.

Free score users (no account)

If you use the free score without creating an account, we store an anonymous analysis profile tied to a session token for up to 48 hours. After 48 hours, the anonymous profile is permanently deleted. We cannot send you legal change alerts without an account, as we have no way to contact you.

Retention periods

• Uploaded files: discarded immediately after analysis (within seconds)
• Anonymous analysis profiles: 48 hours maximum
• Account analysis profiles: retained while your account is active, deleted within 30 days of account deletion
• Payment records: retained for 7 years as required by tax law (Stripe handles card data — we never see it)

Who we are

Patent PreCheck is a Chrome extension and web service that helps individuals track and protect original ideas created with the assistance of AI tools. Patent PreCheck is not a law firm and does not provide legal advice.

What data we collect and how

Data processed locally (never sent to our servers)

The following data is processed entirely within your Chrome browser and stored using Chrome's local storage API on your device:

• The text content of AI conversations on supported platforms (ChatGPT, Claude, Gemini, Perplexity, etc.)
• Your typed messages and the AI responses you receive
• Your scored "journal entries" — the descriptions you write when prompted
• Your Patent PreCheck Score and its component values
• Your position, preferences, and settings within the extension panel
• Filing wizard data you enter (name, address, work title, authorship descriptions)

This data never leaves your device. It is not transmitted to Patent PreCheck servers, cloud storage, or any third party.

Data collected for account and billing (Pro/Filing plans)

If you create an account or subscribe to a paid plan, we collect:

• Your name and email address
• Billing information (processed by Stripe — we do not store card numbers)
• Subscription status and plan history
• Support communications

Analytics and usage data

We may collect anonymous, aggregated usage statistics to improve the product — for example, how many times a particular feature is used. This data is not linked to your identity and does not include the content of your conversations.

How we use your data

• To provide the Patent PreCheck scoring and tracking service within your browser
• To manage your account and subscription if you have one
• To process payments through Stripe
• To respond to your support requests
• To improve the product through anonymous usage analytics

We do not sell your data. We do not use your conversation content for advertising. We do not train AI models on your data.

Interactive Code Review — Paid Tier Data Handling

This section applies specifically to the paid Interactive Code Review service. It is separate from the free Patent PreCheck Score, where your uploaded code is analyzed and immediately discarded without ever being stored on our servers.

What we store during a paid review session

When you purchase and use an Interactive Code Review, we store the following on our servers:

• The text of your answers to the interview questions presented during the session
• Component scores and the aggregate score derived from your answers
• Session metadata: report ID, purchase timestamp, completion timestamp, session state, and the SHA-256 hash and length of the code you analyzed before upgrading

Note: Evidence file uploads and final document generation are not yet part of paid Interactive Code Review sessions. This policy will be updated when those features launch.

Retention for paid review sessions

• Active session window: 30 days from purchase. During this window, you may answer questions, resume from your email link, and finalize the session.
• After 30 days: the text of your answers is permanently deleted. Your scores, completion status, and customer record are retained.

What we retain permanently from paid sessions

• Contact information: name, email address, and billing record
• Report ID and completion timestamp
• Aggregate score and component scores

Encryption and transmission

Paid session content is stored encrypted at rest in our Neon Postgres database. All data is transmitted between your browser and our servers over HTTPS.

Third-party vendors involved in paid sessions

• Resend — transactional email delivery (purchase confirmation, resume link)
• Anthropic — AI scoring of your answers
• Netlify — web hosting

Data sharing

We do not sell or share your personal data with third parties, except:

• Stripe — payment processing for paid plans
• Legal requirements — if required by law, court order, or governmental authority

We do not share your conversation content, journal entries, or filing data with any third party under any circumstances.

Data storage and security

Conversation content and journal entries are stored in Chrome's local storage on your device. This data is not transmitted over the internet and is not accessible to Patent PreCheck or any third party.

Account data (name, email, billing) is stored on secure servers with industry-standard encryption. We use HTTPS for all data transmission.

If you clear your browser data or uninstall the extension, your locally stored data will be permanently deleted.

Your rights

• Access: You can view all data stored in the extension by opening the dashboard at any time
• Deletion: You can clear all local data by uninstalling the extension, or by clearing Chrome's site data for the extension. Account data can be deleted by contacting us.
• Portability: You can download your journal entries and filing summaries from the dashboard at any time

Children's privacy

Patent PreCheck is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us.

Changes to this policy

We may update this Privacy Policy from time to time. We will notify you of material changes by updating the date at the top of this page and, for significant changes, by email if you have an account with us.
